      This is an incredibly awesome piece of art. I can’t believe no one has found it yet… How did you do it?

      Hey, thanks! I set up a program in Processing to grab images from my web cam and output them to the screen; each frame is subtracted from the previous frame on an ongoing basis, just as if you were creating an endless stack of layers in Photoshop, each one set to Subtract or Difference, or whatever they call it.

      Does that make sense?

      It makes perfect sense, just not sure how to actually accomplish it phsically. Did you write a program or di the subtracting manually?

      I wrote a program. Quite a simple one, too. I could send you the code if you like.

      But you have perhaps the worst user name I have ever seen

      Anyway, send me *your* email address if you want code. That makes a lot more sense.
